To all whom it may concern.'

Be it known that I, VILLIAM J. N Esrrr, acitizen of the United States ofAmerica, residing at Los, Angeles, county of Los Angeles, State ofCalifornia, have invented a certain new and useful Heel-CuttingApparatus; andI do hereby declare the following to be a full. clear.-and eXact description of the invention, such as will enable' othersskilled in the art to which it appertains to make and use the same.

This invention relates toimprovements in heel cutting apparatus, and ithas. for one of its objects to provide a novel and improved constructioninv which both the cutter and the shoe holding device are mounted on across arm which is adapted for ready mounting on a supporting pedestalor onthe frame which is already in use and carries other devices foroperating on shoes in doing repair work.

Another object of the invention is to provide a novel and improved shoeholding device.

Further objects of the invention are to provide a novel andv ilnprovedheel cutting apparatus which. is practical and. commercial, simple andcompact in construction, easy to operate, convenient and economical touse, and in which the parts and devices are easily adjustable t0 suitconditions and to make all of the desired straight or angular cutsthrough the heel.

lVith the above and other objects in view the invention may be said toconsist in the provision ofthe novel` and advantageous features and inthe novel and improved construction, arrangement, and combination ofparts and devices as will be apparent from the claims and from a carefulconsideration of the following description of the`preferred,construction of the improved apparatus, taken in connectionwith the accompanying drawings in which Figure 1 isa side elevationalview of the improved apparatus disposed on the frame which carries otherdevices for doing` repair workon shoes; Fig. 2 is a side lelevationalview of theapparatus disposed on a supporting pedestal; Fig. 3 is abroken sectional view taken on the line 3-3 of Fig..

Referring to the drawings, the crossarm 15 has adjustably mounted at theends thereof the mounting 16 for the circular saw 17, and the adjustablemounting 18 for the shoe holdingdevice 19. The crossarm 15 is providedon its underside with the downward extension 20 which is provided withthe groove 21 and is adapted to t in the socket 22.

The mounting 16 consists of the bifurcated bracket 28 which is providedat its upper end with the bearings 24 and is provided at its lower endwith the stem 25 which is slidably fitted in the guideway 26 at one endof the crossarml. The sprocket wheel 27 is feathered on and operated todrive the shaft 28 which is fitted in the bearings 24 and. has one endsuitably attached to the circular saw 17. A set screw 29 on-the erossarm15 is adapted to engage the stem 25 toloek the mounting 16 in adjusted.position on said crossarm.

The adjustable mounting` 18 consists of the stem 80 which has tiltablj7mounted on its upper end the platform 31 on which is slidably mountedthe table 32 on which is pivotally mounted the plate 33 which hasthereon the adjustable bar 34 whichcarries the shoe holding device19.The platform 31has one end of its lower bifurcated part mounted on thepivot 35 on the stein 30, and it has the other end provided with thecurved `slots V3G through which and the stem 30 passes the bolt 37 sothat the platform can be tilted sidewise of the circular saw 17and1locked in adjusted position. The table'32qis-provided on itsunderside with the dovetail guide 38 which is slidably fitted in acorresponding guideway inthe upper partcf the platform 31 so that :thetable 32 can be. movediparallel to the circular vsaw 1'?.Y The table 32has on its flat upper side the pivot 39`to which is connected the platelll@ 33 so that the latter can be turned to 'turn the bar 34 andconsequently the shoe holding device 19 at an `angle to the circularsaw. The bar 34 is disposed parallel to the circular saw 17 and isprovided with a lateral dovetail guide 40 which is fitted in acorrespondiug guidoway in the upper part of the plate so that the bar3ft and consequently the shoe holdingl device 19 can be moved laterallytoward or away from 4the circular saw 17. The plate 33 has on its rearthe extension 41 which has thereon the pivot 42 to which is connectedthe rear end of the lever 43 which has its forward end provided with thehandle 44 and which is provided with a slot 45 through which extends thepivot 46 on the guide 40 so the bar 34 and consequently the shoe holdingdevice can be moved toward or away from the circular' saw 17 byswinging` the lever 43 to the right or to the left. The lever 43 hasthereon the pivot 47 on which is mounted the latch 48 which is pressedby the .spring 19 and adapted to engage the teeth 50 on the forward endof the plate The latter can be turned on the pivot 39 by means of thehandle 51 which has thereon the pivot 52 on which is mounted the latchwhich is pressed by the spring 54 and adapted to engage the teeth 55 onthe table 32 to lock the plate 33 in adjusted position. The. stein 30slidably fitted in the guideway 56 which is provided at onerend of thecrossarin 15, and the latter has thereon the set screw 57 which isadapted to engage the stein 30 to lock thelatter in adjusted position,

The shoe holding device 19 consists of the similar jaws 58 which aremounted on the pivot 59 on the depending lug 60 which is provided on thebar 34; said jaws 58 having adjacent edges 61 thereof formed and adaptedto :[it in the crease between the heel seat and the heel 62 of the shoe63. VThe .jaws 58 are provided with downwardly converging extensions 64between which is interposed the roller 65 which is mounted on the pivot66 on the arm 67 which latter is mounted on the pivot 68 on the lever69. The latter has a handle 70 at its forward end and has its rear endmounted on the pivot 71 on the, lug 72 at the rear end of the bar 34. Aspring 73 suitably connected to the bar 34 and bearing against theunderside of the lever '69 is adapted tonormallyhold the lever 69 andconsequently the roller 65 in the raised position so that the jaws 58Yare normally inthe full open position.

On the4 pivot 74 between the lugs 7 5 and 7 5 on the bracket 23 ismounted the lever 76 which is provided at its lower end with the handle77 and has at its upper end the j yoke 78 which 'is provided with slots79 into which extend the pins 8O on the ring 81 whlch is loosely mountedbetween Kthe colvice 19. to adjust thefheel 62 laterally towa rd or awayfrom the circular saw 17 ,Y the latter when it is found more convenientcan be adjusted relatively to the heel 62 by operating the lever 76 tomove the shaft 28 and consequently the circular saw 17. The lever 76 hasthereon the lugs 84 and 85 on which is slidably mounted the dogV 86which is adapted to engagetheteeth 87 on the lug to lock the lever 76and thus the circular saw 17 in adjusted position. A link 88 ispivotally connected to the dog 86, and the angular operating lever 89which latter is mounted on the pivot 90 betweenthe lugs 91 and 92 on thelever 76. A spring 93 which bears against the lug 84 anda shoulder 94 onthe dog 86 is adapted to normally press the dog 86 into engagement withthe teeth 87.

'A stop 94 on the platform 31 is adapted to limit the rearward movementof the table 32.

As seen in Figs. 1, 3 and 4, the socket 22 may be suitably attached tothe bar 95 on the usual framework 96 which has mounted thereon otherdevices for doing repair work on shoes; or, as seen in Figs. 2 and 9,said socket 22 may be suitably arranged on the upper part of thesupporting pedestal 97. The socket 22 has thereon the set screw 98 whichis adapted to extend into the groove 21 to lock the crossarm 15 inadjusted position.

From the foregoing the construction7 manner of use, and the advantagesof the improved apparatus will be understood by thoseskilled in the arm.1t will be seen that the cross arm 15 can be readily mounted on asuitable support or on the framework which carries other devices alreadyin use for doing repair work on shoes. The mounting 16 for the circularsaw 17 and alsothe mounting 18 for the shoe holding device 19 admit ofadjustment as may be required to suit conditions in installing and usingthe apparatus. After placing the heel part of the shoe 63 between thejaws 58 the lever 69 is moved downwardly to cause the roller 65 to moveagainst the extensions 64 to move the edge portions 61 of said jaws intothe crease between the heel seat and the heel 62 of the shoe 63 so thatthe shoe 63V is held clamped by said jaws.l To make a straight cutthrough the heel 62 the lever 43 is operated to move the bar 34 andconsequently the shoe holding device 19 at a right angle to the circularsaw l17 according to the amount that is desired to" cut off of theheel62, or if found more convenient, themlever is desired to make an angularcut longitudinally of the heel 62 the heel holding device 19 is turnedto the desired angle to the circular saw 17 by the adjustment of thepivoted platform 31. When it is desired to make an angular cuttransversely through the heel 62, the plate 33 is turned by the handle51 to have the heel holding device 19 at the desired angle to thecircular saw 17. After adjusting the heel holding device 19 or thecircular saw 17 according to the cut that is to be made through the heelG2, the table 32 is moved to effect movement of the heel 62 past thecircular saw 17 to have the latter cut said heel.

The construction which has been particularly illustrated and describedadmits of minor changes and modifications-wherefore the right isreserved to all such changes and modifications as do not depart from thespirit and scope of the invention which is defined in the appendedclaims.
